1 Claim.

This invention relates to a combined stop, waste and hot Water drainvalve, the primary object of the invention being to provide a stop valvewhich will operate to drain the hot water 5 pipe lines of the systemwith which the valve is used, simultaneously with the closing of themain or stop valve.

An important object of the invention is to provide a valve body whereinthe drain opening thereof, lies in a plane below the pipes of the systembeing drained thereby insuring against the Water collecting in the valvebody.

A still further object of the invention is to provide a valve whichcloses in a direction with l5 the flow of water under pressure, passingthrough the valve, thereby reducing wear on the valve washer and valveseat to a minimum, and greatly increasing the life of the valve washer.

With the foregoing and other objects in view,

which will appear as the description proceeds,

the invention resides in the combination and arrangement of parts and inthe details of construction hereinafter described and claimed, it beingunderstood that changes in the precise embodiment of the inventionherein disclosed, may be made Within the scope of what is claimed,without departing from the spirit of the invention.

Referring to the drawing:

Figure 1 is a vertical sectional view through a valve constructed inaccordance with the invention.

Figure 2 is a vertical sectional view through the valve, taken at rightangles to Figure 1.

Referring to the` drawing in detail, the valve comprises a body portionindicated generally by the reference character 5, the body portion beingprovided with an inlet opening 6 in which the inlet pipe l ispositioned, and an outlet opening 8, in which the-outlet pipe 9 ispositioned.

As clearly shown by Figure l of the drawing, the outlet opening 8 isdisposed above the inlet opening 6, and above the drain opening ID ofthe valve, so that when the main or stop valve has been moved toitsclosed position, the water from the pipe 9 Will gravitate to the drainopening IB.

A partition II is arranged within the valve body and divides the valvebody into an inlet side and outlet side, the partition providing a valveseat I2 for the stop valve I3, which operates within the inlet side ofthe body portion, and closes in a direction with the oW of water throughthe valve body, thereby reducing Wear on the valve washer and valveseat, to a minimum.

The reference character I4 designates a valve stem that extends into thebody portion through an opening formed in the top of the body portion 5,the body portion being formed with internal threads that cooperate withthe threads I5 of the valve stem, so that rotary movement 5 of the valvestem will operate to raise or lower the valve stem, to control thevalves supported thereon.

Arranged in spaced relation with the valve seat I2, and disposeddirectly thereabove, is a l0 tapered valve seat I6, which tapered valveseat accommodates the valve member I l, which is tapered to t within thetapered seat I6.

The drain opening II) of the valve body, eX- tends entirely through thevalve body, and merges l5 into the valve seat I6, with the result thatwhen the tapered valve member Il has been properly seated, the drainopening will be closed and the flow of water through the drain opening,will be prevented.

As clearly shown by Figure 2 of the drawing, H one end of the drainopening I8 is enlarged and threaded to receive the threaded end of thepipe I8 that communicates with the hot Water pipes of the system withwhich the valve is used.

Thus it will be seen that when the valve Il has been moved away from itsseat, the water in the system With which pipe 9 communicates, will flowthrough the drain opening I8. The hot water in the system will also bedrained through the pipe I8, and drain opening lll, with the reu sultthat the hot and cold Water of the system will be drained from thesystem, by a single operation of the valve.

The arrangement of the` valves I3 and I6, is

such that when the valve 'I3 is in an open posi- 5 tion, allowing thewater to pass through the system with which the valve is used, the valveI6 will be closed, but when the valve I3 has been moved to a closedposition, the valve I6 will simultane- 40 ously move to its openposition, permitting the water to drain therefrom.

The valve stem I4 is formed with threads I9 that t into the tubularvalve support 20, securing the valve support 2|] and its valve I3, tothe 45 valve stem.

The lower end of the valve body portion is closed by means of the cap2l, which when removed, permits of ready access tov the valve I3, tofacilitate repair. 50

The upper end of the valve body is closed byv means of the nut 22 thatsupports the gasket 23.

On the upper end of the valve stem, is a oontrol handle 24, through themedium of which the valve stem and its valves may be operated. 55

opening of the body portion and having a lateral drain opening, a hotwater drain pipe extending into the body portion and in communicationwith the interior of the body portion through the tapered valve seat, avalve stem threaded in the body portion and extending through the valveseats into the bottom of the valve body, a disk valve on the lower endof the valve stem and adapted tov engage the lower side of the firstmentioned valve seat controlling the passage of water through the bodyportion, a tapered valve on the valve stem and adapted to engage thetapered valve seat, said Valves being so arranged that when the diskvalve is closed, the tapered valve is open allowing water to drain fromthe hot Water drain pipe and pipe leading from the outlet opening of thebody portion.
